ENGINE OIL RECOMMENDATIONS
Case IH No. 1 Engine oil is recommended for use in your Case engine. Case IH No. 1 Engine Oil will lubricate your engine correctly under all operating conditions.
If Case No. 1 Multi-Viscosity or Single Grade Engine Oil is not available, use only oil meeting API engine oil service category CH
See the chart below for recommended viscosity at ambient air temperature ranges.
NOTE: Do not put performance additives or other oil additive products in the engine crankcase. The oil change intervals given in this manual are according to tests with Case lubricants.

DIESEL FUEL SYSTEM
Use No. 2 diesel fuel in the engine of this machine. The use of other fuels can cause the loss of engine power and high fuel consumption.
In very cold temperatures, a mixture of No. 1 and No. 2 diesel fuels is temporarily permitted. See the following Note.
NOTE: See your fuel dealer for winter fuel requirements in your area. If the temperature of the fuel lowers below the cloud point (wax appearance point), wax crystals in the fuel will restrict the fuel filter and cause the engine to lose power or not start.
The diesel fuel used in this machine must meet the specifications as shown below in, “ Specifications for Acceptable No. 2 Diesel Fuel ” , or “ Specification D975-81 ” of the American Society for Testing and Materials.
Fuel Storage
If you keep fuel in storage for a period of time, you can get foreign material or water in the fuel storage tank. Many engine problems are caused by water in the fuel.
Keep the fuel storage tank outside and keep the fuel as cool as possible. Remove water from the storage container at regular periods of time.
Fill the fuel tank at the end of the daily operating period to prevent condensation in the fuel tank.
